SPECIFICA 'lION forming part of Letters Patent No. 767,826, dated August16, 190%.

Application led April 1S, 1904. Serial lo` 203,739. (No model.)

To {1,7/ 1.0700711/ 'if mfrrfll/ con cfr/1,:

lle it known thatl, Do'iiINick N Inlinons'r, a citizen ot' theUnitedStates oi' America7 residing at luilalo, in the count),v of Erie andState of New York, have invented certain new and useful .Improvementsinlffuliuttonsof which the following is such a lull, clear` and exactdescription as will enable others skilled in the art to which itappertains to niake and use the same, reference being had to theaccompanying drawings, lorining a part hereof.

The object of this invention is to provide a simple and eflicientfastening Jor cull and collar buttons, studs, and other articles whichWill permit the ready insertion or removal of the article withoutsoiling or injuring the linen or other material to which it is applied.

With this object in view l construct one head ofthe br ton with atubular stein carrying a fastening device and construct the other headwith a sleeve adapted to engage the tu'- bnlar stein and be engaged andheld by the fastening device.

The invention therefore consists in such an arrangement ot' parts and incertain novel features of the saine as will be hereinafter lirst fullydescribed and then particularly pointed out in the claims. v

ln the drawings hereto annexed l have shown the invention applied to alink cull'- button. Y

ln the said drawings, Figure l is a side view ot the button completewith the parts locked together. the sanic. Fig. 3 is a detailviewshowing the parts of the button in perspective and separated7 and Fig. ais an enlarged. detail section of the end of the stein.

ln carrying out the invention l forni on-or securc'lo the head A of thebutton a tubular stern B, which is curved in the form illustrated. Theond el: this steni is provided with external screw-threads C, whichextend to and slightly beyond the end of a longitudinal slot l) in thestein. lVithin the stein is a slidable catch E, consisting' of a pin orsmall rod F, disposed longitudinally within the stein. and a tooth orpawl (l, rising from said pin be- Fig. is a longitudinal section of,`

-catch against the outer end of the slot.

tween the ends thereof and projecting through the slot l). A coiledspring H is litted Within the stein between the head of the button andthe catch and serves 'to normally hold the For convei'iience inassembling l prefer to torni the stein with the slot extending entirelyto its cnd. The spring` and the catch may be then successively placed.in the stein, after which the end of the stein may bc closed bysecuring a bushing l therein. Nithin the bean or base J of thebutton lsecure an internally-threaded sleeve li, having an annular llangc l; onits end, the said flange being foi-ined with a radial notch M, as shown.

The construction and a'rangeinent of the several parts beingl thus madeknown, the eper'ation will be readily understood. Alter the tubularstein has been inserted through the,y

buttonholes or openings in the cull or other article the bean or base isengaged over the end ot' the saine and rotated so that through theaction or' the screw-threads the notched flange will be brought to andagainst the catch, the rcsult being that the catch will automaticallyengage the notch and prevent Yfurther rotation of the bean, Nhen it isdesired to detach the button, the catch is disengaged by a pressure ofthe linger and the bean then rotated in the opposite direction to removethe saine from the stein.

lt will be observed that the notched llange serves as a stop by bearingagainst the outer surface of the bean-to prevent the sleeve dropping toolar into the bean, thereby preventing the end ot the sleeve niarring thebean, and that it-also avoids the necessity oi' Forniing a partei' thelock on the bean. Consequently the invention may be readily applied tobuttons new in use. All the parts are inclosed, so that when the buttonis in use a close inspection is necessary to distinguish it from theordinary solid-stein buttons.

lt will be noticed that one end et' the pin portion ot' the catch litsin the busting in the end ol' the tubular stein, while the other end ot'said pin enters the coiled spring. The ends oi" the pin are thusguided`v so that the catch wiil move eveniy and wabbiing of' die smilewhile the device is in use is avoided.
